OF DAYTON, OHIO INTERLOCKING MECHANISM Application filed June 29, 1928.

The object of this invention is to provide interlocking mechanism whereby the 1mproper sequence of operations of a register is prevented. In the particular register shown by way of illustration in this application means are provided whereby the register may be normally operated to print a record. If desired, a total representing the sum of all previous registrations may be printed and it is possible to reset the totalizer to zero. I have provided locking and interlocking mechanism whereby the machine is locked against operation if any of the setting means for'the register are not properly set. I have also provided spacing mechanism whereby the record paper may be actuated so as to move all of the detail impressions beyond the pointwhere the total impression will be made. Means are further provided whereby the total printing mechanism is rendered inoperative until the spacing mechanism has been fully actuated. I further provide means whereby it is impossible to reset the totalizer until after an impression has been taken therefrom. It is not, however, necessary to reset the totalizer. Locking means are also provided to lock the machine against operation while the impression is being taken from the totalizer. I have also provided means whereby you cannot take a total print or reset to zero unless all money and class levers are in zero position.

Means are also provided whereby the class lever cannot be placed in no sale position unless all amount levers or keys are in zero position.

If it is desired to read the total impression it is necessary to release the retaining pawl of the spacing mechanism and to advance the spacing mechanism again.

Summarizing, means are provided whereby you cannot take a total print unless all money and class levers are in zero position. You cannot take a total impression unless you have properly spaced the record paper. You cannot turn to zero until after taking a total print. You cannot read your total print without releasing the retaining pawl and again spacing the record paper. You cannot partly operate the printing knob and Serial No. 289,278.

then operate the machine. After starting to take the total impression the spacing mechanism is held locked and so are the said levers or keys. All money levers must be in zero position before recording a no sale transaction.

With these and other objects in view as will be more fully explained in the detailed description which follows, I have shown the nism mounted on the left sidewall of the machine.

When a is desired to is. an impression from the totalizer it is first necessary to more all of the levers or keys representing price p or class to zero or home osition. The money levers are indicated in ig. 8 by the reference characters 79 and the class lever is indicated by the reference character 80. In a ticket issuing machine for use on railways the class lever 80 may be used to indicate the various classes of fare such as half fare, round trip; etc., but in cash registers for use in stores the class lever-80 would be used to indicate the various classes of transactions such a! no sale, charge; or it migli't be used (Jo-indicate the clerks number such as A, Ekatc. The money keys or levers 79 may be placed in zero position as shown in Fig. 8 at any time except when the machine is being operated but as each of these levers'is moved to zero position it engages a cam surface 81 on a sliding member 82 which is norsea mally .urged to the left by means of spring 83 engaging a pin 84. These sliding members are best shown in Figs. and 8, and it should be noted that there is one sliding member 82 for each of the money levers. The class lever 80 can now be moved to the position shown in Fig. 8 which corresponds to the position in which it should be placed to inclicate that money is being paid out, which is generally indicated by the words no sale. Ifno sale is being made all of the money levers should be in zero position, and it is impossible to move the class lever to no sale position unless all of the money levers are in zero position for the lever 80 will strike against the shoulder of any one of the money levers 79 unless each of the sliding members 82'have been moved to the right as'viewed in Fig. 8 by its money lever 79. If all of the money levers are in zero position and the shoulders 85 have been moved out of the path of movement of the class lever 80, it can be moved into the position shown in Fi 8, which is the no sale position, but as it is so moved it strikes against the cam surface 86 of the locking member 87, best shownin Fig. 7, moving the same to the left. The locking member 87 is provided with L-shaped slots 88 through which the money lovers 79 pass when being moved to zero position. -When all of the money levers are in zero position and the class lever has been moved to its no sale position the locking member 87 looks each of the money levers in itszero position by its shoulders 89 engaging behind the said money levers. The locking member 87 is provided with slots 90 which receive pins 91 secured to the frame of the machine, which pin and slot connection guides the locking member 87 in its sliding movement. The locking member 87 is normally urged to the right as viewed in Fig. 7 by means of a spring 92 secured to a pin 93 carried by the locking member and a pin 94 carried by a stationary part of the machine. The locking member 87 is also provided with an extension 95 which has a slot 96 which receives a pin 97 carried by a fixed part of the machine. The extension 95 of the locking member 87 is provided with a downwardly extending arm 98 which engages, when the locking member is moved to the left as viewed in Fig. 7, the beveled surface 99 of the locking pawl 100 pivoted on a pin 101 carried by the left sidewall 24 of the machine. This pawl 100 is normally urged in an anti-clockwise direction by means of a spring 208 and is stopped in its counterclockwise movement by means of the pin 78 on the lever 68. The forward end of the pawl 100 normally engages a pin 102 carried by a lever 103 rotatably mounted on the shaft 45, which is the same shaft that carries the gears 56. The lever 103 is a part of the printmg mechanism for the totalizer. It is obvious that the pawl 100 holds the lever 103 against operation unless all of the money levers are in zero position and the class lever is in no sale position, but when all of these levers are in the said positions the locking member 87 is moved to the left as viewed in Fig. 7 and raises the pawl 100 out of engagement with the pin 102 thereby freeing the lever 103.

Before taking an impression from the totalizer it is also necessary to advance the record paper 42. It will be remembered that the record paper 42 receives its impression between the platen 39 and type wheels 41 whereas the printing impression from the totalizer is made by the totalfzer printing wheels 58. It is, therefore, necessary to advance the record paper to the left as viewed in Fig. 1 a distance sufficient to move all of the printed impressions from the type wheels 41 to a point to the left of the printed impression that will be made from the totalizer type wheels 58. The paper is advanced by operating the lever 104 which is attached to a ratchet member 105 by means of a sleeve 106. The ratchet member 105 is provided with teeth 107 and a relatively deeper depression 108. A conventional full stroke mechanism 109 works in conjunction with the ratchet member 105 so as to insure a full operation of the ratchet member 105 by the hand lever 104. The ratchet member 105 is provided with an extension 110 which carries a pin 111 to which is secured a pawl 112 normally held in the position shown in Fig. 3 by means of a spring 113. This pawl actuates a ratchet 114 rotatably mounted on a shaft 115 and is held against retrograde movement by a locking pawl 116. Secured to the ratchet 114 is a chambered disk 117 provided with a circular channel 118 having a radial outlet 119. The chambered disk 117 is also provided with a cam depression 120. A pawl 121 is pivoted on a'pin 122 carried by the left sidewall 24 of the machine, which pawl is provided with an arcuate lug 123 which rides on the periphery of the disk 117 and is pressed downwardly by means of a spring 124 mounted in a stud 125 carried by the left sidewall of the ma chine. As heretofore mentioned the lever 108 carries a pin 102 which pin normally lies in the circular channel 118, but if the disk 117 is rotated so that the radial outlet 119 lies in the path of movement of the pin 102 when the lever 103 is rotated clockwise the pin 102 may pass out of the disk 117 thereby permitting the lever 103 to be actuated.

The spacing mechanism, therefore, normally locks the lever 103 against operation and it can only be freed from its locked position by the actuation of the spacing mechanism. When the hand lever 104 is actuated so as to partially rotate the ratchet member 105 anti-clockwise as viewed in Fig. 3 the pawl 112 actuates the ratchet 114.

At any time after the; hand lever 104 a When themoney levers are in zero position I and the class lever is in no sale position i "Q and when the spacing mechanism has been fully operated, the total-printing impression maybe taken. This isaocomplished byro tating the hand knob '152 secured to a l' 153 which carries a disk1'54 which disk id provided with a V-shagedhotch 155 shnillr to thenotch 21 in the isk 20 carried by'thc a 5 shaft 15. The disk 154 carries a wrist 156 to which is connected it pitman 157 which i is attached to a pin 158 on a lever 159 psi oted on a pin 160 carried by the left sidewall of the machine. The lever 159 is bifurcated at its upper end and receives a pin 161 carried by the lower end of the lever 103.

A sliding plate 162 is provided with slots 163 which receive pins 164 carried by the left sidewall 24 of the machine. This sliding plate is provided with V-sheped ends to conform to the notches 21 and 155. Asthe machine is being operated the righthand emi Y of the sliding member 162 will ride on the erip'hery of the disk 29 which will foroethe is fthand projection thereof into the notch 155 and lock the printing mechanism again. operation. It is obvious,therefore, that the printing mechanism is locked unless all of the money levers are in zero positionf'and the class lever is in no sale position and unless and until the spacing mechanism has beenfully operated and is also looked when the main drive shaft 15 is being operated. 5 If the disk 20 is in the position shown in Fig. 4 and if all other things necessary to permit the operation of the printing mechanism are correctly positioned the knob 152 may be rotated, but when it is, the sliding member 162 is pushed to the right as viewed in Fig. 4 locking the disk 20 and the main drive shaft 15 against operation and the lefthand end of the sliding member 162 rides on the periphery of the disk 154. The lever 159 is provided with a slot 165 which receives a shaft 166 which carries a pinion 167 which meshes with a rack 168 mounted on a shaft 169 (Figs. 3 and 4). The shaft 166 also projects through slots 211 in the sidewalls of the machine, the slots 165 and 211 being the guiding means for the said shaft 166. The shaft is actuated by an arm 179 connected to a lever 171 by means of a spring 172. The lever 171 carries a roller 173 which is actuated by the cam 141. The lever 171 is mounted on the shaft 143 and the roller 175 is normally held in engagement with its cam by means of a spring 174.

The operation of the printing mechanism is as follows: As the knob 152 is rotated in a clockwise direction as viewed in Fig. 3 and in an anti-clockwise direction. as viewed in Fig. 4, the disk 154. is rotated in an anticlockwise direction as viewed in Fig. 4 moving the lower end of the lever 159 to the right while the cam. 175 mounted on the shaft 153 engages the arm 176 of the lever 171 rocking the shaft 169 and rack 168. lVhile the rack 168 is being so moved the shaft 166 is being moved by the lever 159 to the left as viewed inFig. 4 so that the platen 177 mounted on the shaft 166 moves the record paper 42 which passes over the said platen into engagement with the type wheels 58 of the totalizer so that an impression of the total amount registered on the totalizer wheels is transferred to the said record paper. The totalizer wheels are inked by an inking roller 178. A locking pawl 179 is mounted in the path of movement of the cam 175 to prevent retrograde movement.

It is impossible to reset thetotalizer until after the printing operation from the totalizer has been completed for the reason that the arm 180 of the bell crank lever 181 prevents the resetting gear 182 being brought into mesh with the idler gear 183 which idler gear is operatively connected with the printing wheels 58 of the totalizer. The hand knob 184 is provided with a tongue 185 which normally is seated within a groove 186 is a boss 187. The hand knob 184 is secured to a shaft 188 and a spring 189 is interposed between the resetin g gear 182 and the left side wall 24 of the machine which spring normally urges the tongue 185 into the groove 186 provided the said tongue and groove are in alignment with each other, thereby locking the hand knob 184 against rotation. The arm 180 normally lies beneath the shaft 188 and between the sidewall 24 and the gear 182 so that it is normally impossible to move the gear 182 to the left as viewed in Fig. 6 so as to bring it into mesh with the idler gear 183.

A sliding bar 190 (Fig. 4) is provided with a slot 191 which receives a pin 192 carried by the sidewall 24 of the machine. This in and slot connection guides the righthand end of the sliding bar 190 which bar is in the path of movement of the lever 103 and is connected to the bell crank lever 181 by means of a pin 193. WVhen the printing impression is being made the lever 103 moves clockwise and engages the shoulder 195 of the sliding bar 190 moving it to the left as viewed in Fig. 4 and rotating the bell crank lever 181 mounted on the shaft 196 in a counter-clockwise direction so as to remove the arm 180 below the teeth of the gear 182 so that the said gear may be moved by means of the hand knob 184 to the left as viewed in Fig. 6 into mesh with the gear 183. hen the sliding bar 190 is thus moved to the left as viewed in Fig. 4 it is retained in that position by the lug 197 of the bell crank lever- 198 engaging the recess 194 in the sliding bar 190, the said lug 197 being urged toward the bar 190 by means of a spring 199 connected to an arm 200 of the bell crank lever 198 and to the pin 192.

The operator is now free to pull outward ly on the knob 184 so as to bring the gear 182 into mesh with the gear 183 and when he so moves it, the righthand end of the shaft 188 as viewed in 6 is moved out of holding engagement with the lever 201, which lever must be pulled outwardly in order to permit the resetting of the totalizer. However, the resetting mechanism for the totalizer forms no part of this invention and as it is fully shown and described in the co-pending application of Albert S. VVheelbarger and Grover C. Coil, Serial No. 238,662, the description thereof will not be repeated in this application.

From the above description, it is obvious that the totalizer is locked against resetting until the impression has been made from the totalizer. It is, however, not necessary to reset the totalizer even though a total impression has been made, for if the machine is again operated the lug 150 on the lever 148 will engage the arm 202 of the bell crank lever 198 and will raise thelug 197 out of engagement with the recess 194 of the sliding bar 190, and the spring 203 attached to the pins 193 and 192 will pull the sliding bar 190 into the position shown in Fig. 4 and gum 180 upwardly against locking the gear 188 the meehanismimay be 5 nthepawlllti from c =1 releaaedby op- Obviously, th s nmemwmes reach of the operator'and he disengage the said tiimhe pleased.
